IMPROVED SMUT-MAGHIE.

TO ALL WHOM I'l MAY CONCERI: p

Be it known that I, E. McLANE, of Young America, in the county ofWarren, and State of Illinois, have invented a new and usefulImprovement in SmutMachines; andI do hereby declare that the followingis a full, clear, and exact description'thereof, which will enableothers skilled in the art to make and use'the same, reference being hadto the accompanying drawings,` forming part of this specification, inwhich- Figure 1 is a vertical section of my invention, taken in the linex z, iig. 2.

Figure 2, a horizontal section of the same, taken in the line y y, iig.1.

Similar letters of reference indicate like parts.

This invention relates to a new and improved machine for depriving grainof smut and other impurities.

It consists in a scouring-device of peculiar construction, and a novelarrangement of a suction-blast, whereby a very powerful and eiicientblast is obtained without wastingor blowing away the grain, and thegrain scoured in the most thorough manner -by a very compact device. p

In 4the accompanying sheet of drawings, A is a cylindrical case, dividedinto three compartments, a b c, by the horizontal partition-plates'ol d.Thelcwer compartment, c, contains a rotary fan, B, which is keyed on avertical shaft, C, the latter passing through the case A and through acylinder, D, the lower part of which extends down to the bottom of theupper compartment, a, of case A, as shown'inig. 1, the cylinder D beingconcentric with the case A.

The cylinder D contains the scouring-device, which is composed of aseries of plates, E, of circular form, and toothed at their uppersurfaces. 'The outer parts or edges of these plates are turned upward,as shown at These plates E are slightly less in diameter than theinterior ofthe cylinder D, and underneath each cylinder D, and theplates E are secured to the shaft C.

l From the lower end of the cylinder D a spout, G, extends into avertical suction-blast spout, II,`which is at the side of the case A,(see tig. 1.) The upper end of the spout H communicates with the uppercompartment a of case A, the lower end'being open. Within the spout Hthere is a vertical partition, e, which forms a passage, f, a valve, g,being in its upper part. y i

I represents a curved spout, the lower end of which communicates withthe compartment a,-a.nd the opposite end with the top of cylinder D,said tube, just above the cylinder D, being provided with a smallhopper, t. The compartment a has spouts t' extending down from it, witha ilap, 7', at their lower endsto admit of the discharge of substancesat the exterior of the case. The compartments a b communicate witheachother by means oan opening, 7c, (see tig. 2,) and the compartments bc communicate with each other by means of a. central opening, Z. v

The grain to be cleansed passes intothe hopper h, and thence downthrough the cylinder D,and is scoured by the plates E, the grain, as itpasses o` from the edge of one plate, E, being conducted by a spout orconductor, F, downto the centre of the plate E, iinmediately below it. l

The rotation ofthe fanVB-produces a suction in the spouts I and H, inthe direction indicated bythe arrows, said suction drawing the smut andall light impurities from cylinder D into the compartment a.

The cleansed grain falls through the spout G into the passagef of' II,where-it is subjected to a second blast, and any remaining smut, chat?,or light imperfect grain, carried up into compartment a, is dischargedthrough the spouts z', while the smut or light impurities are drawn intoand discharged from the fan-case through aspout, m, communicatingtherewith.V

By regulating the valve y,.t-he amount of light grain to be drawn intocompartment a may be regulated asV desired, and the whole of the lightor inferior grain separated from the scoured grain, or the bestqualitypf the former allowed to remain with the latter.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- Tne passagef in the blast-spout H, provided with thevalve g, when arranged in relation with the spout G and fan ll, tooperate substantially as and for the purpose set forth.
